The truth is, we're all cyborgs with cell phones and online identities.Geoff Johns

Real mobile numbers; no message filtering.

SMS Privacy has always provided virtual numbers. These are numbers that we get from an SMS API provider.
Unfortunately, the API provider blocks the verification codes for signing up to various online services.
There is no way for us to tell in advance what they are blocking, and they can change it at will at any time.

To solve this problem, we now offer physical numbers: we have real mobile numbers, in addition to our virtual numbers.
This
means the API provider can not block you from receiving certain messages. In theory, the mobile network
operator could filter messages, but in practice we have not observed this.
You use it just
like a virtual number, except it's a little more expensive and we only have GB (+44) numbers available.

Get started with a physical number for only 0.003 BTC (the one-time setup fee).
You'll be able to receive messages within minutes, for no extra charge, and you'll have the number on your account
for at least 24 hours.
